RESILIENT TIRE.

Application filed October 11, 1910. ASerial No. 586,533.

- tains to make and use the same.

v double tires.

My invention relates to resilient vehicle tires.

It has for its object to increase the flexibility and durability of the tire.

Other objects will become apparent from the following description.

The invention cosistsin the features of construction, combinations and arrangements of parts, hereinafter set forth, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

- In the accompanying drawing, illustrating the preferred 'embodiments -of my invention: Figure 1 isha broken side view of part of a wheel rim carrying one of my Fig. 2 is a sectional view on the line .2r-m of Fig. 1. Fig. 3 is a sectional view on the line y-y of Fig. 1. Fig. 4 is a detailed View of one of the shield plates, Fig. 5 i's a sectional view similar to Fig. 2 but showin a modified construction of fastening device for securing the outer tire to the flanges, and Fig.- 6' is a cross sectional view.' of a modified form of rim on which no inner tire is used.

Referring more particularly to Figs. 1 to 4, inclusive, of the drawings, 1 designates the felly of the wheel which has outwardly extending Hanges 2 secured to it by anyi suitable means, such as the bolts 3. Between these anges and arranged crosswise'on theouter surface of the felly are'lugs spaced equidistant apart and serving as guides for plates or shoes owhich conform on their` inner faces to thefelly but are flat on-their outer surfaces.- Outwardly extending tables 6 are formed on each of the shoes 5. Said tables are stepped, as' at 7, to provide forv .centering and retaining helical springs 8 arranged interiorly of larger similar springs 8*. The springs of each pair are coiled in opposite directions whereby the force thereof is directed in true radial lines. A bumper 9 of rubber or other-suitable-exible material sgecication of Letters Patent.

is fixed in asocket in the outer faces of each 'a curved outer-surface conforming to therv curvature of the wheel and to the inner surface of the tire. Each of said shoes lOis equipped with inwardly extendinglugs 13, at its extremities, which are guided between the Shanks of bolts 14 y through the flanges 2' at points arranged radially above the lugs 4 on the felly. The shoe 10 is further guided and, retained against endwise movement by a slottedy lug 15, preferably arranged at the middle of passed transversely said shoe, and engaginga bolt 16 also passed transversely through the Hanges 2. Said lugs 15 and bolts 16 also serve to retainth shoes 10 against excessive outward Inovement when the tire is removed. The 'shoes 10 are grooved on their outer faces toreceive the inner tire 17., Plates y18 are let into the under surface of said tire and span the spaces between'the adjacent ends'fof'the .shoes l0 vwhereby `the tire is prevented from entering between said shoes and the unrestricted action ofthe latter is-insured. v'Said plates have lateral flanges 19 arranged at the sides of the shoes and provided with longitudinally extending slot-s 2O in which'project pins 21 secured to the sides of said shoes. Said pins are preferably made in the Vform of screw bolts, as illustrated in Fig. 3, the heads of said 4bolts being 'countersunk in the grooves so' that they will not project beyond the outer surfaces ofthe platea' It will benoted that the slots 20 will allow the shoesto work back and forth towardk and away from one another, and that the bolts will retain said plates inproperfposition and prevent'them from sliding to positions where they would leave the `spacesbet-ween the shoes uncovered. -Each of the shoes -510 is 'provided with 4a longitudinally "extending socketvor chamber 22 in which there ishoused y a coiled spring 23. v One end y24 of'each'shoe is closed, while I its other end 25 is' open. Made integral with the closed end or secured thereto in anyr suitable |manner there is .a

projecting lug 26 of arcuate shape to .con-

.form tothe curvature of the wheel rim. This lug extends into the open end 25 of the -adjacentx'shoe 10,.- and is provided with a flange, 27 on its extremity. Said lugs 26 hold their shoes in uniform alinement, while allowing 'them to move toward and away from one another, and retain the shield plates 'fiat and straight at all t-imes.

j The spring 23 in each shoe bears against the closed end of its shoe and against the flanged ext-remity of the lug of the adjacent shoe which projects into the open end of its shoe. The tendency of said springs is, therefore, to keep the shoes expanded at a uniform distance apart all around the wheel and to give more elasticity to the wheel. A stop or projection 28 is arranged in the open end of each of the shoes to prevent the lug 26 from being entirely withdrawn therefrom by engaging the flange 27. Said projections 28 also hold the ends of the lugs 26 olf of the inner edges of the shoes so they will not jam when telescoped. The outer tire 29 is placed enlarged beads 30 formed thereon.

over the inner tire 17 and secured to the outer edges of the flanges 2 in the manner illustrated in Fig. 2. It will be observed that. the lateral edges of said outer tire have These beads-are tted in the grooves of channeled strips 31 having flanges 32 and 33 at the op- 'posite edges of their grooves or channels 34. Said strips are secured to the flanges 2 by bolts 35 and 36 passed respectively through their inner flanges 32 and outer flanges 33. The bolts 36 in the outer flanges 33, of necessity, also pass through the outer tire outside or above the beads 30. It will thus be seen that the fastening, just described, very used.

firmlysecures the outer tire to the flanges and will prevent dust or dirt from entering the interior where it would be apt to clog or otherwise impair the operation of the springs. l

The modified construction illustrated in Fig. 5, relates to the manner of securing the outer tire to the flanges 2. As shown in this ligure, a flat strip 37 is used instead of the channeled strip shown in Fig. 4. The edges of the tire 29 are placed between the strips 37 and the edges of the flanges 21and'secured to the latter by means of bolts 38 passed through all three. This construction is simpler than that illustratedin Fig. 2, and is very eflicient.

As illustrated in Fig. 6, the inner tire may be dispensed with and only the outer one he word tire as used in the appendedlclaims should, therefore, be understood asl meaning either a double tire or a single oijter tire.

When/the outer tire is used' alone, the telescoping' shoes are made to conform to it on their/outer surfaces, as at 39 in Fig. 6. In

.this arrangement, the shield plates 18 are preferably let into the outer tire, as at 40.
